Are there some global warming deniers that have some political weight?

Answers

The republican strategist Frank Luntz advised Republicans to continually challenge the science behind global warming. Also, lobbyist Philip Cooney edited out portions of scientific reports to make the results seem to deny global warming. Both of them had incredible impact in the late 90s and into the 21st century, but have less of a voice now. Currently more pundits than politicians are taking on this subject, and many of them have an incredible following.
